释放由 ToolStripItem 占用的非托管资源,还可以另外再释放托管资源。Releases the unmanaged resources used by the ToolStripItem and optionally releases the managed resources.

 override void Dispose(bool disposing);
protected override void Dispose (bool disposing);
override this.Dispose : bool -> unit
Protected Overrides Sub Dispose (disposing As Boolean)

此方法由公共Dispose方法Finalize和方法调用。This method is called by the public Dispose method and the Finalize method. Dispose调用受保护Dispose(Boolean)的方法, disposing并将参数true设置为。Dispose invokes the protected Dispose(Boolean) method with the disposing parameter set to true. FinalizeDispose 设置disposingfalse的情况调用。Finalize invokes Dispose with disposing set to false.

disposing 参数为 true 时,此方法释放该 ToolStripItem 引用的、由任何托管对象持有的全部资源。When the disposing parameter is true, this method releases all resources held by any managed objects that this ToolStripItem references. 此方法调用每个引用对象的 Dispose 方法。This method invokes the Dispose method of each referenced object.


Dispose 可以由其他对象多次调用。 Dispose can be called multiple times by other objects. 重写 Dispose(Boolean) 时,请注意不要引用在以前调用 Dispose 时已释放的对象。When overriding Dispose(Boolean), be careful not to reference objects that have been previously disposed of in an earlier call to Dispose. 有关如何实现Dispose(Boolean)的详细信息, 请参阅[实现 Dispose 方法](~/docs/standard/garbage-collection/。For more information about how to implement Dispose(Boolean), see [Implementing a Dispose Method](~/docs/standard/garbage-collection/ 有关DisposeFinalize()的详细信息,请参阅[清理非托管资源](~/docs/standard/garbage-collection/和[重写 Finalize 方法](。For more information about Dispose and Finalize(), see [Cleaning Up Unmanaged Resources](~/docs/standard/garbage-collection/ and [Overriding the Finalize Method](
